Glad to help a fellow Electrolux enthusiast, Francois, and nice to be appreciated!
Thanks for posting the "nice old lady's" photo of her advertising photo. That's the best kind of person from whom to buy as generally they take good care of their belongings and routinely have them checked and serviced.
It's great that you have the matching Sidekick 1562, and the power nozzle 1692. All original is nice, but so is an upgrade such as a matching-colored pn with a headlight.
I have a 1692 with my Ultralux LX 1521 and am pleased with its performance.
Side note: Only the later Diamond Jubilees, Marquises, Grand Marquises, and Legacys had the small crevice tool clip (in addition to the small combo tool clip), because they were supplied with the shorter crevice nozzle. The early- to mid-Diamond J's, Ultraluxes, Ultralux LX's, Ultralux Classics, and Ultrlux CE's had the classic longer crevice tools (aka narrow space cleaners), so the crevice clip was removed from their handle design. Most don't seem to know about it. In fact, the lady's photo is the only personal one I've ever seen that shows it being used.
